29 Claims.

. been used from time to time for lengthening the reach of a mans arm into the cylinder, but they have not usually been satisfactory.

An object of the invention is to provide a new and improved automatically unloading mechanism, particularly for use with an open-ended machine.

With this object in view, a feature of the invention contemplates the provision of a new and improved'chute that may be removably inserted into the inner cylinder of the machine, at the end of the operation of treating the contents thereof, to enable discharging or unloading the contents.

Other and further objects will be explained hereinafter and will be particularly pointed out in the appended claims.

The invention will now be more fully described in connection with the accompanying drawings, in which Fig. 1 is a view, partly in side elevation, partly in vertical longitudinal section, and partly in transverse section, of a tumbling machine of the above-described character, the longitudinal section being taken upon the line I-l of Fig. 2, looking in the direction of the arrows, the chute being removed, and the end doors of the inner cylinders being shown closed; Fig. 2 is a vertical transverse section taken upon the line 2-2 of Fig. 1, looking in the direction of the arrows, also with the chute removed; Fig. 3 is an end elevation of one of the inner cylinders or drums, the view being taken from the open end of the cylinder, and showing the removable chute in place above the goods contained in the cylinder; Figs. 4 and 5 are respectively side and end elevations of. the preferred chute; Fig. 6 is a view similar to Fig. 3, but showing the chute commencing its unloading operation; Fig. 7 is a view of a detail, upon a larger scale, showing the small end of the chute held in place; Fig. 8 is a view similar to Figs. 3 and 6, showing the chute in its final unloading position, with the contents of the cylinder sliding from the chute into a t: uck, illustrated in dotted lines; Fig. 9 is a fragmentary longitudinal section similar to Fig. 1,

As in application, Serial No. 281,255, filed June 26, 1939, now Patent 2,360,377, entitled Washing machine, of which the present application is a continuation-in-part, a machine is shown, provided with an upright outer closed, stationary, generally cylindrical, casing or housing having a centrally disposed sectionlO, bounded by oppositely disposed end walls l6 and I1. Axially alined cylindrical end-section chambers 5 and 6 for containing a washing, degreasing or other fluid are disposed at the respective ends of the centrally disposed section, the end-section chamber 6 beyond the wall l6 and the end-section chamber 5 beyond the wall H.

The walls l6 and I! are respectively secured to the end sections 6 and 5. Circular or cylindrical angle-iron reinforcing rings or bands ll, L-shaped in cross section, are welded throughout to the respective walls l6 and H of the end sections 5 and 5, in axially alined relation thereto. Gaskets (not shown) may be interposed between the iron rings I I and th walls I6 and I1, respectively, to render th joints tight. Circular or annular bolting-ring members 202 are welded along their inside edges to the inner surfaces of the centrally disposed section II). Weld joints are shown in the drawings black.

The centrally disposed section II) is illustrated as further provided with a lower side-segment portion l2, of rectangular cross-section, that is secured, in any desired way, as by welding, to a base 15 by which the centrally disposed section In is thus directly supported. The side segment I2 is secured, as by welding 4, to the annular members 202 which, in turn, support the side walls I 6 and I1. The end sections 5 and 6 are supported directly by portions l4 and I3, respec through sealed openings in the walls l6 and I1,

respectively beyond these walls, into the respective end sections 8 and 5.

Inner perforated tumbling drums or cylinders l8 and IQ, for containing materials to be washed, degreased or the like, are respectively fixed to the outer ends of the shafts 28 and 30. The cylinder I8 is thus axially journaled to rotate with the shaft 29 in the end section 6 of the housing, and the cylinder i9 is axially journaled to rotate with the shaft 3% in the end section 5 of the housing. The cylinders are thus axially alined, and each is provided with an inner end wall 39 and an outer end wall 50. As will be more fully explained hereinafter, the outer ends of the shafts 29 and 30 are fixed to the respective cylinders I8 and H9 at their innerend walls 39.

The inner end of the shaft is shown in Fig. l disposed within a split hub 23. The inner end of the shaft is similarly shown disposed within another split hub 28 that is alined with the first-named -split hub 23. The alined split hubs Z3 and 2B are secured together into a unitary hub structure by means of bolts passing through pairs of alined bolt openings 25, on opening 25 of each pair in each of the split hubs 23 and 28. After the alinedshafts 28 and 39 have been mounted in this unitary split-hub structure 23. 28, with their inner ends adjacently disposed. they are securely fastened therein in any desired manner, as by means of bolts extending through alined bolt openings $1 in the ends of the respective split hubs 23 and 28. To guard against accidental rotation of the shafts 29 and 30 in the hubs 28 and 28, a. key I may be inserted in splines 31 in the shafts and corresponding splines 2 in the hubs. p

The shafts 29 sandal! become thus rigidly coupled together intermediately between the cylinders l8 and is to rotate as a unitary shaft in single shaft, is to facilitate disassembly, for purposes of repair. The rotation of the shaft 29. all may be effected by means of a driving gear wheel 27 that is fixed to the unitary-hub structime 23, 28 so as to rotate between the bearings 8i and 32. The gear 21 is shown as driven from an electric motor 25, mounted upon a non-cylindrical upper portion 29 of the centrally disposed housing section Iii. Through belts 22, the motor 2i drives a pinion 25 that, mountedupon a drive shaftfl, meshes with the gear 21.

Rotation of the driving gear 2! by the motor 2! is thus communicated, through the unitary shaft 29, 30, to the inner cylinders l8 and i9, which are thuslikewise rotated in unison. The machine is thus'in perfect balance, each cylinder T8 or 15 serving as a coimterweight for the assume to carry a load of from seven hundred to a thousand pounds each. It is accordingly possible to provide these outer walls each with an axially disposed circular discharge opening 4|, and the outer walls of the end sections 5 and 6 each with a concentrically disposed axially alined discharge opening l2. The hides, skins, laundry and the like may be inserted into the respective cylinders l8 and I9, and removed therefrom, through the two pairs of alined registering openings or orifices t2 and M. The washing, degreasing or other fluid in the end sections 5 and 6 may enter the cylinders l8 and I9 through their perforations and through their openings 4 I.

Each opening 42 may be closed, during the ,operation of the machine, when the contents of the cylinders are tumbled, by a frusto-conical door 44, hinged at one side, and provided with means for holding it securely in place at its other side. An annular projection in each opening 42 is adapted to engagea compressible ring seal that is disposed in a circular recess in each door as. Each door 64 is provided, along its periphery, with a cylindrical projection 5| that, when the door is closed, is disposed in a cylindrical projection 58 mounted correspondingly along the periphery of the corresponding opening GI.

In order that the cylinders l8 and i9 may be enabled the better to carry the heavy loads contained therein, without destroying their balance, and without the necessity for employing any additional bearings at 'theouter endsof the cylinders, it is desirable to reinforce their inner end walls 39. As these end walls 39 are duplicates, it will sumce to describe one only. Ac-

cording to the specific embodiment of the invention that is illustrated and described herein, each end wall 39 is reinforced by a circular spider lilfl that is held securely thereagainst by rivets NH. This spider comprises radially disposed reinforcing T-beams Hi2 that are welded at their outer ends to the inner walls of an outer ring I84 and at their inner ends to the. outer walls of a concentrically disposed inner bushing I06. The T- beams are shown in Fig. 1 adjacent to walls 39.

Six such T-beams may be employed, with adjacently disposed T-beams reinforced by connecting L-beams. The bushing IDS is welded to the inner ends of the T-beams I62, both directly. and also through the medium of an annulus H0. Radially disposed lugs'or fins H3 are welded to the T-beams m2 at the faces thereoffopposite to the faces that carry the legs of the T's, and

end sections 5 and E with bearings for such such shafts, and this even though the cylinde s may be of considerable size, say, suihciently large also to the outer surface of the bushing Hill- The lugs H3 are shown in elevation in Fig. l. The shafts 29 and 30 are shown each extending through two annuli m and IE8 that are welded to the inner walls of the respective bushings .896.

The outer end of each bushing WE extends into an inset or re-entrant portion H2 of the wall dathat is shaped frusto-conically to receive the fins "3. The smaller base of the frustum is flat to receive the outer end of the bushing 1'06 and the abutting outer end of the shaft 23 or 30 that is disposed therein, as hereinaftermore fully described. A fitting R8,, provided with a longitudinally extending opening, for cooperatingv with an unloading chute, as hereinafter more fully described, extends through arr-opening in the smaller flat base of the re-entrant frustum portion 2 and into the outer end of the shaft 28 or 38. I.

' The-inner end'of the bushing E85 is secured. as by welding, to an annulus tit, to which is welded a flange lid. The inner diameter of the II 8 through which the shaft 29 or 30 extends, and

to which the shaft 29 or 30 is secured in any de? sired manner, as by welding. The annulus H8 is reinforced by a number of ribs .I22 which may be welded both to the shaft 29 or 30 and the annulus H8. The annulus H8 is detachably fastened to the annulus H4 in any suitable manner, as by means of machine screws or bolts I20. This detachability enables the parts to be readily separated, as for purposes of repair.

To disassemble the machine, the screws or bolts 8 and 9 are first removed. This makes it possible to remove the and sections 8 and 5 from the central section I 0, leaving the cylinders I8 and I9 intact on their shafts. It is necessary also to unbolt the split-hub structure 23, 28. Access to the central section I0'may be obtained, for this purpose, through doors 200. The cylinder I87and the shaft 29 upon which it is mounted may then be removed by pulling to the left. as viewed in Fig. 1. The cylinder I9 and the shaft 30 upon which it is mounted may similarly be removed by pulling to the right. Unscrewingof the bolts or screws I will make it possible to detach the shaft 29 and its annulus IIB from the cylinder I8. I

A bushing 36, disposed centrally of each of the walls I8 and I1, is rigidly secured thereto at its inner end, as by welding. An inwardly projecting annulus 35 is shown welded to the inner end of the bushing 36. The bearings 3| and 32 are each provided with a bushing I29, for housing bearing rollers I3I, and 'each having a flange I that abuts against an annulus 35. The flanges I30 are detachably secured to the annuli in any desired manner, as by means of bolts or screws I32. The manner in which the bearings are sealed is substantially the same as disclosed in the said application. The purpose of the seals, which are of circular shape, as shown. and are pressed into their respective housings, is toretain the grease and exclude dirt and other matter from the bearings. Each seal comprises a steel outer casing 206, an annular leather ring 208, and a steel spring 2I0 for maintaining a constant pressure of the leather against the shaft. The leather ring 208 is so constructed that the seals act also as stufling boxes to prevent the entrance of air during the hereinafter-described evacuation process. The end walls I6 and II of the centrally disposed sect on I0 are shown reinforced by means of webs 33 and 34 that respectively radiate from the bearings 3I and 32.

It is customary, in machines of this character, to provide more or less equally spaced, longitudinally disposed, cleats, shelves or baiiies that project a shortv distance interiorly into the inner cylinders from the cylindrical walls thereof. The baffles, preferably of U-shaped cross-section, are illustrated as of alternately large and small size, the large-size baflles I42 projecting'into the cylinder a greater distance than the small-size baflies I44. Each large baflie I42 is disposed diametrically opposite to a small baflie I44.

Let it be assumed that a large bailie I42 occupies its lowermost position. In this position, it will be effective to raise a load of skins. hides or laundry at the bottom of the cylinder. During the rotation of the cylinders'by the motor 2|, say, anticlockwise, as viewed in Fig. 2, this large baffle I42 will ride up along th right-hand wall of the cylinder to engage the skins, laundry or or other contents thereof. As it engages them. it

' Welded to the other end of the wall 68.

will raise them up. carrying them around along the inside of the cylinder. After they have risen to a height determined by the speed of the machine and the size of the bailles, they will drop back toward the bottom of the cylinder, on to the next adjacen-tly disposed smaller baflle I44. This results in tumbling the skins or the laundry, as a v consequence of which they become intimately admixed with different portions of the liquid contained therein.

Steam may be supplied to the liquid contained in the end sections 5 and I5, for heating the contents of the cylinders I8 and I9, through steam-inlet conduits or pipes I33 that are connected to heating jackets I34 and I36. The jacket I34 is shown provided upon the lower portion of theend section 6 and the jacket I38 on the lower portion of the end section '5. The jackets I34 and I36 are shown provided with drains 204.

The lower end of each of the walls I5 and I1 is provided with a shelf 65, supported by an up standingprojection 66. One of the projections 86 is .welded to one end of a lower wall 68, shown constituted of the upper wall of a cylindrical chamber I84. An L-shaped flange member I0 is The V L-shaped member I0 may be secured to the other projection 66 by bolts or the like 69, that may be removed for purposes of disassembly. A duct chamber I is thus provided under the right-.

hand, shelf 65, and to the right of the right-hand projection 65, as viewed in Fig. 1. and a duct chamber I82 is similarly provided under the lefthand shelf 65, and to the left of the left-hand projection 68. The chambers I80 and I82 are in' the form of rectangular boxes, welded in'place in suitable openings of the walls l8 and II. The outer vertical side walls of the chambers I 80 and I82 are shown at 2I2, the inner vertical walls are shown at 65, their upper walls are provided by the shelves 65, nd a continuous lower wall of the chambers is shown at 2I4. The chamber I80 communicates with the end section 5, the chamber I82 communicates with the end section 5, and the chambers I80 nd I 82 communicate with each other through the cylindrical chamber I84. The chamber I84 is in the form of a circular pipe, welded. as before explained, in a wall opening of the chamber I80, and bolted to a wall openingln the chamber I82. The chamber I80is connected with an outlet water drain or evacuating line I85 shown disposed laterally of the casing I0, adjacent to the bottom thereof, and the chamber I02 with a solvent drain I88 for both end sections. The chambers thus serve as a drain; and also to equalize the level of the liquids in the sections 5 and 6.

Water may be supplied to the end sections 5 and 6 through a water-inlet pipe I90, and the solvent and the emulsifier through a solvent-inlet pipe I92.

After the end sections 5 and 6 have been filled to the desired level, the skins or hides are tumbled by rotating the gear 21, to rotate the cylinders in their respective end sections, as before described.

After the hides or skins have been thus tumbled. and after the water and solvents contained in the end sections 5 and 8 have been drained, it is found advantageous to subject the hides or skins to the action of a vacuum. This may be effected,

, the doors 44 being closed at this time, by pumping out the air. The air may be pumped out of the end section 6 through a pipe I96. Under the tracted from the hides or skins, the closed end sections and 6 at this time constituting 'a drying chamber. As the hides or skins become cooled, in consequence, it may be desirable to add further heat during the evacuation, as by supplying steam to the jackets I34 and I36, or by introducing hot water into the end sections 5 and 6. One should be careful, however, not to supply so much heat as to injure the skins or hides. During this evacuating operation, the cylinders may be rotated, if desired; preferably, as during the tumbling, in the same direction continuously.

The vacuum in the end sections 5 and 6 may later be broken by admitting air through an air inlet valve I 98.

The size ofthe cylinders, in machines of this character, has heretofore been restricted, among other reasons, by the fact that their unloading has been performed manually. A workman can not reach with his arm very far into the cylinder to remove the contents thereof. According to the present invention, however, provision is made for unloading the cylinders automatically. This makes it po$ible to increase materially the size of the machine.

This unloading is effected with the aid of a 'novel removable unloading chute 41. The chute is more or less funnelor cone-shaped, having surfaces angulated with respect to the axis of the cylinder, and its axis substantially alined with the axis of the cylinder. In its preferred form. the funnel or cone is not circular in cross-section; the cross-section is of varying curvature. The curvature is sharper or greater along the bounding side element I56 than along the opposite bounding side element I66, and is of least sharpness in between; that is, the smallest radius of curvature is along the element I58, a larger radius of curvature along the element I68, and still larger radii of curvature in between. As clearly appears from the drawings, however, the radii of curvature are not the same at all points of the elements I58 and I66 and in between. For example, the radius of curvature at the end of the element I58 bounded by the smaller end I62 of the cone is smaller-than the radius of curvature at the outer edge I65. Also, the radius of curva-' ture at the end of the element I60 bounded bythe smaller end IE2 is less than the radius at the outer edge I66. For any cross section, however,

This construction renders the chute flatter in between the bounding side elements I58 and I68 than at these bounding elements. The chute is provided with a longitudinally disposed lip or shelf I63 along the bounding side element I60. for engaging a milk: I42, as presently'to be described.

I The smaller end I62 of the cone is provided with a perforated ear 53 that is adapted to be alined with the before-mentioned opening in the perforated plug I28. A pin I64, inserted through the perforated ear 53 and into the opening in the plug I28 at the axially inner end of the cylinder, will hold the chut in place in the cylinder, with the larger end I66 of the chute disposed in the opening 4| and engagingly supported by the lower wall of the opening 4|- Though thus held in place by the pin I64 and the said lower wall of the open action of this vacuum, the solvent is readily exing 4|, so :as to rotate with the cylinder, the chute is free to rotate axially of the cylinder about the pin I64. The concave side of the chute, when the chute is thus held in position by the pin I64. slopes or slants or tapers downward in an axially outward direction from the axially inner end of each cylinder near the car 53, toward the discharge openings 4| and 42.

Upon the completion of the treatment of the materials contained in the cylinders I8 and I9.

the motor' 2| is stopped, and the doors 44 are opened. The unloading chute 41, which is nor- -mally outside the cylinder during the tumbling operation, in order not to interfere with the tumbling, is then removably inserted into each cylinder through the openings 4| and 42, in the space above the contents of the cylinders, with the convex side of the chute upward, as illustrated in Fig. 3. The pin I64 is inserted through the opening in the ear 53, and the motor 2| is restarted. The shelf |63, it will be noted, is shorter, at the shoulder I65, than the bounding side I68. in order that the outer edge I66 of the chute may extend through the openings 4| and 42, while the shelf I63 is entirely within the cylinder, in engagement with a battle I42.

As the cylinder rotates, anti-clockwise, as

viewed in Figs. 3, '6 and 8, the lip or shelf I63 will at first rotate through a part revolution past a small baille I44. It-will, however, soon engage a large baiiie I42. It rotates past this small baiiie I44 because the lip or shelf I63 on the chute 41 is just long enough to engage with this'baflle I42, which is considerably longer than the bafiie I44. After this engagement with the large baiile I42, the chute 41 will rotate with the cylinder. In Fig. 3, the lip or shelf I63 is shown previously positioned in engagement with a large bafiie I42. The engagement of the bafile I42 by the shelf I63 will prevent further rotation of the chute with respect to the cylinder. During the further anticlockwise rotation of the cylinder by the motor 2|, therefore, the chute will be actuated, con-- cylinders I8 and I9, their contents will slide down- 7 along the chute 41, through the openings 4| and 42, and into a truck 52 that may be positioned adjacent to these openings 4| and 42.

After the cylinders have become thus automatically unloaded, the chutes may be removed therefrom, and the machine prepared for another operation.

It will be obvious that, since the cylinders I8 and I9 rotate as a unit, it will be necessary to use right-hand and left-hand chutes in the respective cylinders. One of these is shown in Figs. 3, 6 and 9 in the cylinder I9. If the chute shown in Fig. 9 were used in the cylinder I8. obviously its'convex side would be downward in Fig. 3, instead of its concave side. as illustrated.
